, UNITED STATES FFICEQ ATENT GOVERNOR FOR STEAM-ENGINES AND OTHER MOTORS.

.1 3"OIPICATEON forming part of Letters Patent No. 307,268, dated October 28, 1884.

Application filed July 10, 1884. n model To all, whom, it may concern:

Be it known that I, CARL AUGUST CHAI- NEUx, a subject of the King of Prussia, residing at Aachen, in the Province of Rhenish Prussia, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Governors for Steam-Engines and other Motors, of which the following is a specification.

This invention ha's'for its object to provide a novel governor for engines; and it consists in the mechanism hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figurel is a front elevation, partly in seo tion. Fig. 2 is a side elevation. detail view of the spindle.

Similar letters indicate corresponding parts.

The letters \V indicate a governor, which may be made of a usual formas, for example, two weights actuated by centrifugal force. A pulley, T, with suitable gears, or other convenient arrangement, may be applied for opcrating the governor \V.

To the governor \V is connected by suitable n1cansas, for example, a collar, 72, and links we u:a spindle, s, which rises and falls with the increase or decrease in speed of the governor \V. The governor XV causes the spindle s to rise and fall, but without revolving the spindle.

The letters Z) 0 indicate two actuating or bevel wheels, the axes of which are hollow or made in form of a collar, and sit loosely about the spindle s, so that said bevel-wheels I) 0 can revolve freely on said spindle 8 without turning the spindle. The bevcl-wheels I) c are revolved in opposite directions by a bevel-wheel, a,with which they gear, and which bevel-wheel a. is revolved by a pulley, 0, receiving motion from any convenient source. a

On the collar or axle of each bevel-wheel b c is a coupling device, g, which, in the example shown in the drawings, is formed by a notch or notches cut into the outer edge of each such collar or axle.

On the spindle s are coupling devices 0 f, adapted to engage with the coupling devices 9. These coupling devices cf are shown as being formed'of collars, which are feathered 011 the spindles s, so as to slide thereon, but which spindle s.

Fig. 3 is a Patented in Germany Mat-ch31, 1880, No. 13,555.

collars cannot revolve independently of the These coupling devices cf are held in position on the spindleby springs, as shown in the drawings,which springs allow the coup lers cf to he slid out of place and return them to their original position when free. The couplers e f are such a distance apart that when the governor \V holds the spindle s in such a position that the couplers 5 lie midway between the couplers c f the couplers g, e, and f are out of engagement and the bevelwheels I) 0 do not revolve the spindle s. This relative position of parts is that adapted to the machine when at its proper degree of speed. An increase of speed causes the governor XV to raise the spindle s and bring the coupler f into engagement with the coupler of the bevel-wheel 0 when the spindles begins to turn, and a screwihread at the end of said spindle s, engaging a nut or slide, 76, causes said nut or slide 7,: to move longitudinally and actuate a lever or arm, t, which may connect with a valve to shut off or diminish the supply of power. A decrease of speed causes the governor W to allow the spindle s to descend, and brings the coupler 0 into engagement with the coupler y of the bevel-wheel b, turning the spindle in the opposite direction, and causing the slide it" to move in a direction opposite to that referred to in connection with the bevelwheel 0, and causing the arm or levertto open or increasc the supply of power. \Vhen the slide It has risen to its highest point, anincline, i, on said slide 7,: strikes against the arm Z of the detent-lever Z m and presses said arm Z outward, forcing inward the arm on. The end of the arm Zrests in a groove in the slide 7;. By this motion of the arm m a stud or pawl is forced into the path of a detent-arm, a. This detent-arm a is rigidly attached to the wheel a or to its axle, and when the arm m forces the detent-stud into the path of said detent-arm a it arrests the revolutions of said arm a and the revolutions of the bevel-wheel a and its axle. The detent-arm a may be formed of a plain strip or rod, of metal or other suitable material, firmly fixed or keyed to the bevel-wheel a or to its axle, so as to revolve therewith. The pulley-wheel 0, which revolves the axle of the bevel-wheel a, is mounted on a sleeve having a projection, p,

which engages with a recess on the axle of the wheel a, so as to cause the pulley 0 to turn the wheel a. On the revolutions of the wheel a and its axle being stopped by the detent n, the pulley 0 continues to revolve, said pulley 0 and its projection 12 move or slide outward against the resistance of the spring on the outer side of the pulley 0, and said projection 12 passes out of engagement with the notch on the axle of the bevel-wheel a. At the same time a stud, a, on the sleeve of pulley 0 is brought into contact with the hammer-arm q of an alarm, thus sounding the alarm and giving notice of the stoppage of the bevelwheel a. The upper end of the slide k is provided with an incline similar to the incline i, and when the slide L reaches its lowest point the bevel-wheel a is again stopped and the alarm sounded. The arm 1 is shown as being a bellcrank lever. In place of this the lower end of the slide 7t may be provided with a rack,which gears into a pinion or cog-wheel, which wheel may serve the purpose of the lever or arm t,- or the screw end of the spindle, instead of moving a slide, may engage with a cog-wheel and revolve the same.

In Fig. 3 is shown the spindle s as being provided with longitudinal slots or holes,into

or through which may pass studs on the coupling-sleeves e f, whereby the couplers ef are compelled to turn with the spindle s, at the same time being free to move longitudinally on the spindle. Fig. 8 also shows part of the screw-thread at the end of the spindle 8.

That I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a governor, V, a spindle, 3, connected therewith, actuatingwheels I) a, revolving in opposite directi ons, and

a bevel-wheel, a, of a slide, It, having a screwconnection with the spindle, and provided adjacent to each of its ends with an incline, 7;, and a detent mechanism actuated by the inclines to stop the rotation of the said bevelwheel, substantially as described.

2. The combination, with a governor, WV, a spindle, 8, connected therewith, actuatingwheels I) c, and bevel-wheel a, of a slide, it, connected with the spindle,anda detent mechanism operated by the slide to stop the rotation of the said bevel-wheel, substantially as described.

3. The combination, with a governor, \V, and a spindle, .9, provided with coupling de vices e f,held in place by springs,of actuatingwheels I) c, revolving in opposite directions, and provided with coupling devices g,adapted to engage alternately with the coupling de vices Substantially as set forth.

4. The combination, with a governor, \V, and a spindle, s, of actuating-wheels b 0, revolving in opposite directions, and adapted to engage alternately with said spindle s and a detent apparatus, 1 m a, substantially as set forth.

5. The combination, with a governor, \V. and a spindle, s, of actuating-wheels b 0, re volving in opposite directions, and adapted to engage alternately with said spindle s. a detent apparatus, and an alarm, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. I
